Graco 25P566 PTFE Ball Kit Overview
The Graco 25P566 is a replacement 3-inch PTFE check ball kit for compatible Graco SaniForce sanitary pump systems. The check balls are used within the pump's fluid valve system to support controlled, one-way fluid movement during operation.
PTFE construction provides strong chemical resistance and is suited to demanding fluid transfer applications where compatible wetted components are required. This kit is intended for maintenance and replacement of worn or damaged check balls in approved pump configurations.

Purpose of the Check Balls
Check balls are important components in an air-operated double diaphragm pump. As the diaphragms cycle, the balls seat and unseat within the fluid valve system to help maintain directional fluid flow through the pump.
Worn, damaged, or chemically incompatible check balls may affect pump priming and fluid transfer performance. Replacing the check balls with the correct material and size helps maintain the intended operation of the pump.
Key Features

- Graco replacement kit for compatible pump configurations
When to Replace the Ball Kit
Inspect the fluid check balls during scheduled pump maintenance or when fluid transfer performance changes. Replacement may be necessary if the balls show visible wear, deformation, surface damage, or deterioration caused by the pumped material.
Pump priming issues, reduced flow, or inconsistent operation may also indicate that fluid check components require inspection. Always evaluate the complete valve assembly and related components when servicing the pump.
Installation and Maintenance
Before servicing the pump, shut down the system and follow the applicable pressure relief and maintenance procedures. Inspect the ball seats and other fluid valve components for wear or damage when installing the replacement kit.
Confirm that PTFE is compatible with the fluid being transferred and install the components according to the requirements of the specific SaniForce 3250 pump configuration.
